Motorized, height-adjustable desktop system

Abstract

A motorized desktop stand unit having a main surface assembly designed to accommodate a monitor or laptop and a secondary surface assembly designed to accommodate a keyboard. The desktop stand unit also has a frame assembly having an upper frame and a lower frame. An elevation mechanism is provided between the upper frame and lower frame. A switch provided in the main surface assembly, when actuated, causes the elevation mechanism to adjust the space between the upper frame and lower frames, changing the height of the main surface assembly.

What is claimed is: 
     
       1. A motorized desktop stand unit comprising:
 a main surface assembly designed to accommodate a monitor or laptop, the main surface assembly having left, right, front, and back sides relatively to a user of the monitor or laptop; 
 a secondary surface assembly attached to, parallel to, and extending toward the user from the front side of the main surface assembly; 
 an upper frame attached to the bottom of the main surface assembly and a lower frame adapted to rest on an upper surface of a work area; 
 an elevation mechanism provided between the upper frame and the lower frame; and 
 a switch; 
 wherein the elevation mechanism comprises two pairs of scissor arms, wherein each pair of scissor arms is attached on one side of the upper and lower frames and wherein the distal ends from the attached ends of each pair of scissor arms are free to move toward and away from the one side of the upper and lower frames; and 
 wherein when the switch is actuated, the elevation mechanism adjusts the space between the upper frame and the lower frame, changing the height of the main surface assembly above the upper surface of the work area. 
 
     
     
       2. The motorized desktop stand unit of  claim 1 , wherein the elevation mechanism comprises a linear actuator. 
     
     
       3. The motorized desktop stand unit of  claim 2 , wherein when the switch is activated, the linear actuator retracts or extends to cause the distal ends of the two pairs of scissor arms to move toward or away from the one side of the upper and lower frames, thereby either raising or lowering the main surface assembly. 
     
     
       4. The motorized desktop stand unit of  claim 1 , further comprising a transverse reinforcer element, wherein the transverse reinforcer element is attached from a first arm of a first pair of scissor arms of the two pairs of scissor arms to a first arm of the second pair of scissor arms of the two pairs of scissor arms.
